Pedigree of Kindred 4415 Exhibiting Variable Expressivity and Associated KCNJ2 Mutation
(A) Females are denoted with circles and males with squares. An “*” denotes an individual that was not included in the genome-wide linkage screen.
(B) Sequence chromatograph of an affected individual with an A to T transversion corresponding to the D71V mutation.
(C) Amino acid alignment of one subunit from each of the seven members of the inward rectifying K+ channels. The mutation is denoted above the alignment. Lowercase letters denote conservative amino acid changes, whereas a “.” denotes a nonconservative amino acid change

5. Figure 4 Additional AS Kindreds with Identified Mutations in Kir2.1
Females are denoted with circles and males with squares. The kindred number and mutation are denoted above each pedigree. De novo mutations occurred in kindreds 3856, 2679, 6515, 2681, and “Unknown” individuals are those for whom we have no clinical data

Mutations of Kir2.1 in Andersen's Patients Occur in Highly Conserved Residues
Chromatographs of the nucleotide sequence corresponding to each mutation are shown. *Nucleotide sequence shown is the reverse complement of coding sequence. Below each chromatograph is an alignment of the first member of all human Kir families. Mutant residues are denoted above each alignment. “Δ” marks a deletion of the residue below it. Lowercase letters denote conservative amino acid changes, whereas a “.” denotes a nonconservative amino acid change

7. Figure 6 Functional Effects of D71V and R218W KCNJ2 Mutations
(A) Instantaneous current-voltage relationships for oocytes injected with WT (filled squares), D71V (open triangles), and coinjected WT and D71V (filled circles) KCNJ2. Currents were elicited by step depolarizations from −150 to 0 mV, from a holding potential of −70 mV. No detectable K+ currents were observed following injection of D71V alone, while coinjection of WT and D71V induced small, inwardly rectifying K+ currents.
(B) Instantaneous current-voltage relationships for oocytes injected with WT (filled squares), 1/2 WT (down triangles), R218W (up triangles), and coinjected WT and R218W (filled circles) KCNJ2. Injection of R218W alone failed to induce detectable K+ currents. Oocytes were injected with 23 ng total cRNA, with the exception of 1/2 WT that was injected with 11.5 ng WT cRNA. Currents induced by injection of 11.5 ng WT were approximately one-half that induced by 23 ng WT Kir2.1. Data represents mean ± SEM, n = 8–10 oocytes each group
